[Vala] Loop not found?

[Yu Feng <rainwoodman gmail com>]

Dear list,

I was trying to catch up with recent vala master branch, but I get this
error:

valacodevisitor.vala:308.34-308.37: error: The type name `Loop' could not be found
        public virtual void visit_loop (Loop stmt) {
                                        ^^^^

valasymbolresolver.vala:383.35-383.38: error: The type name `Loop' could not be found

Nevertheless git reports the working copy is uptodate and clean.
valaloop.vala is in the source file list.

I was using 0.7.3. Did I miss a release?

Regards,
